IMPRVEMENT IN BALING-PRESIS'ES.

Specification forming part of Letters Patent No. 181,554, dated August 29, 1876; application filed l February 25, 1876.

pressure is removed more than is necessary.

I employ smooth platens and divided hoops, soA that the hoops `are laid upon the lower platen and upon the bale. The pressure is applied to the bale, the hoops are folded at both sides `of the bale to a gage, and then baleties are used to unite the hoops at each side of the bale. By this arrangement the bale is fheld nearly of the size to which it is compressed, and the usual loss by expansion is avoided.

In the drawing, Figure lis a vertical crosssection, showing the folding devices. Fig. 2

is a horizontal section; and Fig. 3 is an in-y verted plan of a portion of the upper platen.

The lower platen a, and head-block b, are united by the tie-rods o, and the platen l is actuated by a screw or other power of any suitable character, and f represents' the bale being pressed. Upon the platen a, at each side, is the gage-plate e, that is grooved to receive the hoops t', and determine their position. The bale f is rolled in upon these hoops after they are in place; the gage-plates e are free from the bale, and held by studs at their ends in line with the-inner edges, which studs.

enter grooves in the blocks e. rThe folding plates g are hinged at their inner corners to the bars h, and these bars h are upon the rods k that slide in holes in the platen d, or they may be supported inv any other convenient manner, so as to be moved in or out, according to the width of the bale. Upon these plates g there are bars i', with hooks 2 passing through mortises in the plates g. These y hooks are positioned to correspond with the grooves in the plates o, and the hooks serve to support the upper hoops l, the same being laid above the hooks so as to be supported by them until the platen is pressed against the bale and holds the hoops in position, after which the bars t" are moved endwise to draw the hooks from beneath the hoops, so that the hoops are free to be bent down against the sides of the bale by turning the plates g down. They swing upon their centers in the bars h in being moved up or down, and it is to be understood that the bars h are pressed toward lthe bale so that the folding-plates g will bend the hoops closely against the sides of the bale. The length of the upper hoops l is to be predetermined by their ends being folded over in a separate machine, so that when the said hoops l are folded down against the sides of the bale, they will all be at a uniform height. It will now be apparent that the length of the lower hoops 'i must be determined, so that when the bale is pressed and the hoops folded up against the sides of the bale, their ends will reach the ends of the hoops Z, and be in a position to receive the bale-ties.

To effect this object I employ the following means: The sliding bars r r are connected by.-

the cross-bar r', and upon the bars r there are journal-boxes s for the folding-bar s', and upon this folding-bar s are the folders t, each of which'folders is made as a hook-shaped block projecting laterally from the stock that is screwed to the bar s', so that the hoops can be laid beneath these folders t, and then by means of a rule or gage the distance between the platen a and the ends of the hoops l can be measured, and the sliding bars r drawn out or pushed in until the edges of the folders t are away from the bale the proper distance; then the folding-bar s is partially revolved by the lever u, and the ends of the hoops t'- are folded over, as shown in Fig. 1. The foldingbar s is then moved endwise in` its journalboxes s to unhook the folders from the hoops, and the plate e is then turned up against the side of the bale', carrying with it the hoops i, which are brought up to the required proximity to theends of the hoops Z for the'bale-tie to be used in uniting the ends of such hoops. It will be apparent-that any suitable baletie may be employed to unite the loops at the ends of thehoops, and that the ends of the hoops are to be broughtmore or less closely together, according to the tie employed.

I find it convenient to mark upon the col-y nus or tie-rod c the feet and inches or other visions, as shown, and these measurements fe to be numbered from the bottom up, so as i easily see the height that there is from le platen a to the loops at the ends of the )per hoops l, and a sliding gage, w, similarly arked and numbered from the end next the 11e, serves to determine the corresponding stance to which the slide r is to be moved r placing the folders t at the place Where e hoop 11 is to be bent.

This improvement may be applied to platensl ready grooved, in which case the hoops will a where the surface of the platen is plain in ead of hein g laid in the grooves as heretofore.

I claim as my invention- 1. The plates g hung by hinges and swingg near the upper edges of the bale, in comnation with the slide-bar i', and hooks 2, Lbstantially as and for the purposes set forth. 2. The folding-bar s', with the folders t, .rning and sliding in bearings s, in combina- .folding-bar to produce the length required in the hoops, substantially as set forth.

5. An adjustable `folding mechanism applied to a baling-press for folding the ends of the hoops, in substantially the manner set forth.

J. A. BOSTWIGK.
